Second additional patent to No. 27232 of September 9, 1883.

Patented in the German Empire on March 13, 1884. Longest duration: September 8, 1898.

Fig ι. Is a horizontal sectional view, and Fig. 2 is a vertical sectional view cd one is through the end into the earth to alternate ends of the wooden beam, which is covered with sheet iron such as FIG. 4, for protection against putrefaction and sponge formation.

The horizontal section, Fig. 1, goes according to Fig. 2 and 3, through an annular channel a _x b _iu which on the sides within the sheet iron cladding with channel depressions C ₁ d _L C ₁ / Ί on the wood and with the corner channels C ₂ d ₃ e _2/2, which latter lead to the lower end of the timber is in communication.

FIG. 5 is a horizontal section according to e - /, FIG. 6 is a vertical section according to i - k through the end of an annular wooden beam to be placed in the ground, which is clad with sheet iron according to FIG.

The horizontal section Fig. 5 goes according to e - /, Fig. 6 and 7, above ground level through an annular channel e _x f _x , which inside the cladding with channel depressions g ₂ KI ₁ M ₁ on the wood and on the outer rings with the channels ik and I ₁ A _{1 is} in connection.

The woods are now impregnated with sulfuric acid before the cladding, then after the cladding and fastening in the ground, the resulting ring and longitudinal channels C ₁ U ₁ e _x /, C ₂ d ₂ f ₂ e ₂ , Fig. 1 , and g ₃ ^ ₂ I ₁ M ₁ ik 2, / £] filled with a mixture of iron ore and iron filings and the corners protruding from the sheet iron cladding ede /, Fig. 1, and gh Im, Fig. 8, to cover the filling, bent inwards, as can be seen in the vertical sections, FIGS. 2, 3 and 7.
